LocationListener 내에서 이중 설정하기

Question

이상한 변수 설정 문제가있는 것 같습니다. 제대로 업데이트하고 현재 위치를 올바르게 설정하는 LocationListener가 있습니다. 나는 현재의 위도/경도를 포함하는 전역 변수를 설정하려고 시도하는데, 어떤 종류의 코드를 게시 한 후에는 그 이상이 실패합니다.

나는 조각이

public class MyMap extends MapFragment { 
    private LocationManager mLocManager; 
    private LocationListener myLocationListener; 
    protected volatile double lat;//Place to hold variable 
    protected volatile double lon;//Place to hold variable 

    public void onActivityCreated(Bundled savedInstanceState) { 
    super.onActivityCreated(savedInstanceState); 
    int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this.getActivity().getApplicationContext()); 
    if (resultCode == ConnectionResult.SUCCESS){ 

     if(gmap == null){ 
      gmap = this.getMap(); 
      if(gmap != null){ 
       gmap.setMapType(GoogleMap.MAP_TYPE_NORMAL); 
       gmap.setOnMarkerDragListener(this); 
       gmap.setMyLocationEnabled(true); 
       gmap.setOnMapLongClickListener(this); 
      }else{ 
       return; 
      } 
     } 
    }else{ 
     GooglePlayServicesUtil.getErrorDialog(resultCode, this.getActivity(), RQS_GooglePlayServices); 
    } 
    distance = 100; 
    myLocationListener = new MyLocationListener(); 
    mLocManager = (LocationManager) this.getActivity().getSystemService(Context.LOCATION_SERVICE); 
} 

@Override 
public void onResume() { 
    super.onResume(); 
    mLocManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 500,10, myLocationListener); 
    mLocManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 500, 10, myLocationListener); 
    mLocManager.getLastKnownLocation(Context.LOCATION_SERVICE); 

} 

@Override 
public void onPause() { 
    super.onPause(); 
    mLocManager.removeUpdates(myLocationListener); 
} 

//Listen for location changes and update the map with that information 
private class MyLocationListener implements LocationListener { 

    @Override 
    public void onLocationChanged(Location location) { 
     if (Math.abs(location.getLatitude()) > 0.0 && Math.abs(location.getLongitude()) > 0.0) { 
      lat = location.getLatitude(); 
      lon = location.getLongitude(); 
     } 
     //This reports correctly 
     Log.v("Magic", "LOCATION CHANGED!" + "\nLat: " + Double.toString(lat) + "\nLon: " + Double.toString(lon)); 
     if (!currentLocationSet) { 
      gmap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(lat, lon), 15)); 
      currentLocationSet = true; 
     } 
    } 

    @Override 
    public void onStatusChanged(String provider, int status, Bundle extras) { 

    } 

    @Override 
    public void onProviderEnabled(String provider) { 

    } 

    @Override 
    public void onProviderDisabled(String provider) { 

    } 
} 
public void newPlace(final UpdatePlacesCallBack upc, Place p) { 
    //This gives me 0.0 for both variables. 
    Log.v("Magic", "Name: " + p.getName() + "\nLat: " + Double.toString(lat) + "\nLon:" + Double.toString(lon)); 
}  

} 

그럼, 어떻게하면 내가 LocationListener 내에서 로그를 볼 때 정확한 위치를 기록 할 것이다,하지만 나는 이중 위도의 값을 검색하려고 경우 double lon 두 변수 모두 0.0을 반환합니다.
